Adjustable Oak Pallet Lamps

I made these lamps well over ten years ago. I got the plans for the tall one from a woodworking mag. Sorry, I don’t recall which one. I actually made two of the tall ones. We needed a table lamp at the time also. So,I drew from the plans and instead of making everything square I gave it a triangle theme. All the wood came from oak pallets my work was throwing out. The height of all the lamps are adjustable by loosening the nobs at the front.
